IMPROVEMENT IN PAPER-CUTTING MACHINES.

Specification forming part of Letters Patent No. 1 72.020, dated January11, 1876; application filed May 14, 1875. v

To all whom it may concern Be it known that I, ANSON HARDY, ofAuburndale, in the county of Middlesex and State 1 which form a part ofthis specification:

My invention relates to an improved method of operating and adjustingthe table or bed of paper cutting machines, so that it can be moved withease and precision, free from any hitching or other irregularity ofmotion, in a parallel direction to the beam on which the cutting-bladeis attached or moved, and which holds the said table or bed securely atany desired point without other fastening.

Figure 1 is an oblique view of the frame of a machine on which rests andmoves the carriage A, to which is attached the wooden table or bed B, asshown in Fig. 2.

On the carriage A .is a cross-bar, (l, on which is cut or cast aworm-thread, E, operated by the hand-wheel F; and having its hearings inthe frame of the machine is a rod or shaft, 1), on which is cut ascrew-thread, matching and working into the worm-thread on the bar 0,and thus moving the table or bed,'on'which rests the stock to be cut,back and forth in a plane parallel to the cutting-edge, with greaterprecision and smoothness than by any other means, thereby obviatingthrowing out of jog the pile of paper, pamphlets, or books which isplaced in position to be out, and materially enhancing the usefulnessand value of the machine.

The relative position of the screw-shaft D to the worm-bar G is such, asof itself to fasten or hold the table or bed B in any desired positionsecurely against being moved, save only by turning the screw-shaft D atthe will of the operator.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the screw-shaft D, the bar 0, and the worm-thread Eon the frame or carriage A, and the table or bed B, so that whenoperated the said table or bed will move with ease and precision in aplane parallel to the cutting-edge, substantially as described.

ANSON HARDY.
